Hi Olivier, I can only receive one time for each load. In order to update the latest values I need to load the program again and again. Can you please help me? Or you have any suggestion?

Sweet Jesus !

I got it finally !!!

The problem was that I need to put the flag "m_xfer_done" to 0 at the beginning of HDC2080_trigger_measurement() so when the loop comes back at the beginning the program doesn't throw an error. In fact the error must have been related to an incomplete I2C transaction hence the necessity to put the flag to "0".

Now I can see the values changing when I put my finger on the sensor.
